Backup Path Operation

Figure 3-3 shows an example of what happens with a cable break or
removal. For any cable break, the SL16 MAUs on either side of the
break would autowrap. In the example, a break in the cable
connecting MAUs 1 and 3 would autowrap the Rin port on MAU 1
and the Rout port of MAU 3. LEDs on either side of the break would
identify where the loss of signal occurred. These autowraps bring the
backup paths into the loop (dashed lines), replacing the lost cable
connection. Both devices automatically return to the primary ring
following a repair.
